Ethereum's Corporate Whale Club: 7 Public Companies Hoarding 6% of All ETH

Public companies have graduated from Bitcoin-only treasuries to a full-blown Ethereum accumulation society. According to StrategicETHReserve.xyz, the listed corporate whale pod now collectively controls over 7.3 million ETH—worth north of $16 billion at current prices—which works out to a chunky 6% of the entire supply. That's a lot of digital real estate for a boardroom.

1. BitMine Immersion Technologies (BMNR) – Guided by Fundstrat’s ever-bullish Tom Lee, BitMine executed a hard pivot from Bitcoin mining to an aggressive ETH acquisition spree, fueled by a $250 million PIPE deal in July 2025. The firm now boasts a stack of 4,595,562 ETH (worth roughly $10.5 billion), accounting for a staggering 3.8% of all circulating ether. Its stated goal is to capture 5% of the total supply, because why own a slice when you can own the whole pie? Recent moves include scooping up another 60,999 ETH and pulling off a $20 billion equity raise, a figure that started at a mere $4.5 billion. DropsTab data, however, highlights the not-so-fun side of the trade: unrealized losses exceeding $7 billion. Lee, undeterred, maintains his famous prediction that ETH could one day reach $60,000, a price target that would make even the most diamond-handed degen blush.

2. Sharplink (formerly SharpLink Gaming) – This company swapped gambling for a different kind of high-stakes game, now holding 869,154 ETH ($1.86 billion). That's about 87% of its audacious 1 million ETH target. The chairman is none other than Ethereum co-founder and ConsenSys CEO Joe Lubin, which is about as insider as it gets. Sharplink raised $400 million via a direct offering and has plans for up to $6 billion more through stock sales. Under new CEO Joseph Chalom (ex-BlackRock), the firm initiated a $1.5 billion share-buyback program and has already bought back $32 million worth of its own stock. In a move that screams "productive asset," the company deployed $200 million of its ETH into DeFi protocols on ConsenSys-incubated Layer-2 Linea, where it also holds a seat on the consortium. The corporate line? A laser-focus on ETH for long-term shareholder value, because sometimes the simplest strategy is just to buy and not sell.

3. The Ether Machine – Born from the merger of The Ether Reserve and blank-check firm Dynamix, The Ether Machine reported a holding of 498,600 ETH ($1.07 billion) as of November. Co-founder Andrew Keys personally contributed a cool 170,000 ETH to the treasury. The firm's mission is to "put ETH to work" through staking and on-chain strategies, because letting billions sit idle is just poor form. Its October staking efforts alone generated 1,350 ETH ($5.5 million) in yield. The ticker symbol changed from DYNX to the more on-the-nose ETHM, and with an SEC S-4 filing pending, a public listing is expected by the first quarter of 2026.

4. Bit Digital (BTBT) – This former Bitcoin miner has fully embraced the role of ETH accumulator, now holding 155,434 ETH ($333 million). The company exited its mining operations entirely, redirecting capital towards ETH and AI compute via its majority stake in WhiteFiber (WYFI). The catch? Its average acquisition cost sits at $3,045 per ETH, leaving the firm approximately $140 million underwater compared to current prices—a painful reminder that even corporate whales can buy the top.

5. Coinbase – The exchange's latest quarterly filing shows it holds 151,175 ETH ($324 million), up from 115,700 ETH at the end of 2024. Coinbase also maintains a stash of over 14,000 BTC, securing its position as a top public holder of both major crypto assets. It's the ultimate "we'll custody it for you, but we're also keeping some for ourselves" play.

6. BTCS Inc. – Blockchain Technology Consensus Solutions reports holdings of 70,322 ETH ($151 million). The firm employs a "DeFi/TradFi" model, actively deploying its ETH on-chain. In a nod to degens everywhere, it also added three Pudgy Penguins NFTs to its balance sheet in August. Shareholders are treated to a "Bividend" of $0.05 per share paid in ETH
